Kristina Yasuda:

Placeholder issue. There used to be a proposal to define PARM - Pushed Authorization Response Mode \(name not final\). The idea was to enable AS/SIOP to send large responses by reference, just like the Client can pass requests with large sizes using PAR - Pushed Authorization Request via `request_uri`. 

AS/SIOP would send `response_uri` to the Client in the response, Client can retrieve response object from the response\_uri.

Additional benefit was security, since what started as a cross-device flow could end as a same-device flow - the user would start the flow by scanning a QR code on another device, but would end on a device used to present the Credential which would open `response_uri`.
